Description

Ng Kong Beng Public Lecture Series

Overview

Abstract of the talk: Mobile devices along with wearable sensors facilitate our ability to deliver supportive behavioral treatments to users anytime and anywhere. These treatments can include a wide variety of content such as cognitive, behavioral, social and motivational support. These interventions are being developed and employed across a variety of health fields, including to improve medication adherence, encourage physical activity and healthier eating as well as to support recovery in addictions. Critical questions in the optimization of mobile health interventions include: “Which type of mobile health notification or text message is most beneficial?” and “Does the individual’s current context such as location, time, mood impact the usefulness of the mobile health notification?” In this talk we discuss the micro-randomized trial design and associated data analyses for use in optimizing mobile health interventions. We illustrate this approach with the micro-randomized trial of HeartSteps, a physical activity mobile intervention.
